158 Controls in detailAutomatic transmission*One-touch gearshifting 
Even with an automatic transmission you 
can change the gears manually when the 
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to 
the left in theD-direction.
The transmission will shift from the current 
gear to the next lower gear. This action 
simultaneously limits the gear range of the 
transmission (
page 159).Upshifting
Briefly press the gear selector lever to 
the right in theD+direction.
The transmission will shift from the current 
gear to the next higher gear as permitted 
by the shift program. This action simul-
taneously extends the gear range of the 
transmission.Canceling gear range limit
Press and hold the gear selector lever 
in theD+direction until
D reappears in 
the multifunction display.
The transmission will shift from the current 
gear range directly to gear rangeD.
Shifting into optimal gear range 
Press and hold the gear selector lever 
in theD-direction.
The transmission will automatically select 
the gear range suited for optimal 
acceleration and deceleration. This will 
involve shifting down one or more gears.
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced 
vehicle control. Your vehicle’s ABS will not 
prevent this type of loss of control.
iTo avoid overrevving the engine when 
the gear selector lever is moved to 
theD-direction, the transmission will 
not shift to a lower gear if the engine’s 
max. speed would be exceeded.

!
Coasting the vehicle, or driving for any 
other reason with gear selector lever 
inN can result in transmission damage 
that is not covered by the 
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle with the gear 
selector lever not fully engaged in positionP 
is dangerous. Also, positionP alone is not 
intended to or capable of preventing your 
vehicle from moving, possibly hitting people 
or objects.
Always set the parking brake in addition to 
shifting to positionP (
page 54).
When parked on an incline, turn the front 
wheels towards the road curb.
Do not park this vehicle in areas where 
combustible materials such as grass, hay or 
leaves can come into contact with the hot 
exhaust system, as these materials could be 
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the 
SmartKey from the starter switch, take it 
with you and lock the vehicle. Do not leave 
children unattended in the vehicle, or with 
access to an unlocked vehicle. Children 
could move the gear selector lever from 
positionP, which could result in an accident 
and/or serious personal injury.

The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the transmission in gear.
Hold the vehicle with the brake.
When you stop longer with the engine 
idling or on an uphill gradient:
Move the gear selector lever to 
positionP.
Set the parking brake.Maneuvering

e.g. when pulling into a parking space:
Control the vehicle speed by gradually 
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.

Automatic antiglare rear view mirrors*
The reflection brightness of the exterior 
rear view mirror on the driver’s side and 
the interior rear view mirror will respond 
automatically to glare when
the ignition is switched on
and
incoming light from headlamps falls on 
the sensor in the interior rear view 
mirror.
The rear view mirror will not react if
reverse gearR is engaged
the interior lighting is turned on
Warning!
G
The automatic antiglare function does not 
react if incoming light is not aimed directly 
at sensors in the interior rear view mirror.
The interior rear view mirror and the exterior 
rear view mirror on the driver’s side do not 
react, for example, if the rear window 
sunshade* is in raised position.
Glare can endanger you and others.Warning!
G
In the case of an accident liquid electrolyte 
may escape from the mirror housing if the 
mirror glass breaks.
Electrolyte has an irritating effect. Do not 
allow the liquid to come into contact with 
eyes, skin, clothing, or respiratory system. 
In case it does, immediately flush affected 
area with water, and seek medical help if 
necessary.
Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror 
surface is convex (outwardly curved surface 
for a wider field of view). Objects in mirror 
are closer than they appear. Check your 
interior rear view mirror or glance over your 
shoulder before changing lanes.!Electrolyte drops coming into contact 
with the vehicle paint finish can be 
completely removed only while in the 
liquid state and by applying plenty of 
water.
